Abstract
La presente invención se relaciona con una espuma depoliuretano que sea apta para entrar en contacto con una herida, la espuma citada teniendo una densidad de por lo menos 0,28 g/cm3 , dicha espuma conteniendo menos de 1% por peso de alcoholes solubles en agua, y además la espuma citada contendrá por lo menos 1% por peso de uno o más ácidos no volátiles farmacéuticamente aceptables.Adicionalmente provee un método para elaborar una espuma de poliuretano apta para ser utilizada como una superficie que entra en contacto con una herida, del citado método comprende:la mezcla de una aparte por peso de un prepolímero recubierto con un isocianato que comprenda entre 0.5 y 4.8 meq. Grupos de NCO/g que contengan entre 0.4 y 1.0 partes por peso de agua y una cantidad efectiva de ácido no volátil farmacéuticamente aceptable, para formar la mezcla del prepolímero;permitiendo que la citada mezcla del prepolímero se cure y forme un producto espumoso;seguido de el secado del producto espumoso.The present invention relates to a depolyurethane foam that is capable of coming into contact with a wound, the aforementioned foam having a density of at least 0.28 g / cm 3, said foam containing less than 1% by weight of soluble alcohols in water, and in addition the aforementioned foam will contain at least 1% by weight of one or more pharmaceutically acceptable non-volatile acids. It also provides a method for making a polyurethane foam suitable for use as a surface that comes into contact with a wound, of said method comprises: mixing a separate by weight of a prepolymer coated with an isocyanate comprising between 0.5 and 4.8 meq. NCO / g groups containing between 0.4 and 1.0 parts by weight of water and an effective amount of pharmaceutically acceptable nonvolatile acid, to form the prepolymer mixture; allowing said prepolymer mixture to cure and form a foamy product; followed of drying the sparkling product.
